ABSTRACT:
A process for the preparation of hydrocarbon solutions of monofunctional amine initiators of the following general structures: ##STR1## wherein M is defined as an alkali metal, selected from the group consisting of lithium, sodium and potassium, Q is a saturated or unsaturated hydrocarbyl group derived by incorporation of a compound selected from the group consisting of conjugated diene hydrocarbons and alkenyl substituted aromatic hydrocarbons; Z is a hydrocarbon tether group which contains 3-25 carbon atoms; A is an element selected from Group IVa of the periodic table and R.sup.1, R.sup.2, and R.sup.3 are independently selected from hydrogen, alkyl, substituted alkyl, cycloalkyl, aryl or substituted aryl groups, m is an integer from 0 to 7, and n is an integer from 1 to 5, monofunctional amine initiators produced by the process, use of the initiators in a polymerization process and polymers produced by the polymerization process.
